Answer:
27 FT
Step-by-step explanation:
Area of square = L × W
= 4.5 ft × 4.5 ft
= 20.25 ft
Area of parallelogram = bh (base times height)
= 1.5 ft × 4.5 ft
= 6.75 ft
Total area = 20.25 ft + 6.75 ft
= 27 ft

Step-by-step explanation:
trianges area= 1/2 times base times hight
That's A because the segmento B represents the "time" he stayed at the Red light

![\tan3\theta=\dfrac13](https://tex.z-dn.net/?f=%5Ctan3%5Ctheta%3D%5Cdfrac13)
Recall that the tangent function has a period of
so that
![3\theta=\tan^{-1}\dfrac13+k\pi](https://tex.z-dn.net/?f=3%5Ctheta%3D%5Ctan%5E%7B-1%7D%5Cdfrac13%2Bk%5Cpi)
for any integer
. Then
![\theta=\dfrac13\tan^{-1}\dfrac13+\dfrac{k\pi}3](https://tex.z-dn.net/?f=%5Ctheta%3D%5Cdfrac13%5Ctan%5E%7B-1%7D%5Cdfrac13%2B%5Cdfrac%7Bk%5Cpi%7D3)
We get 6 solutions in the interval [0, 2π) for
